Answer:
day 14 , 450 dollars
Step-by-step explanation:
We called x is the number of days
Zippy Rent-a-car: 25x + 100
Speedy Rent-a-car: 30x + 30
25x + 100 = 30x + 30
25x -30x = 30 - 100
-5x = -70
x = 14
Given:
The inequalities are:
or 
To find:
The solution for the given inequalities and graph the solution.
Solution:
We have,
or 
Solve the above inequalities separately.

Divide both sides by -5.

...(i)
And,

Divide both sides by 2.

...(ii)
From (i) and (ii). we get
or 
The interval notation of the solution is
.
The graph of the solution is shown below.
Answer:
g(x) = f(x) + 18
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees.
Obtuse angles are greater than 90 degrees, so there's no way
to add two of them together and get a sum that's smaller than
either one already is.
The answer to the question is 'No'.
